ZVISION: Directly access _globalState instead of using setStateValue

setStateValue does a _referenceTable lookup and potentially adds Puzzles
to _puzzlesToCheck. We know that _referenceTable and _puzzlesToCheck
with be cleared during ScriptManager::changeLocation(), so using
setStateValues ends up just being wasteful.
